is exporting objects discouraged? for example:

primary: {
   all my primary stuff 
}
secondary: {
 all my secondary stuff
}

instead of prefixing all exports with

primary

and

secondary

? and I am not really sure if i can access them with

stack.Output('primary.something')

I don't think

stack.Output('primary.secondary')

will work, but you can ask for just 'primary' and it should return a map object of all the other fields.
